This invention relates to wall constructions for aeroplane fuselages. For various reasons' it is desirable to insulate aeroplane bodies vor fuselages against heat or cold,

5 because of the temperature conditions met with in the use of such machines. and it is the object of the present invention to provide means for doing this, thereby preventl ing excessive heat exchange or conduction m between @the interior and the exterior' of the fuselage This object is accomplished by making a double walled fuselage or'body with a vvacuum between the walls, the. heat insulating i5 properties of a` 'vacuum being well-known. At the ysame time. collapse of the walls must be prevented incident to the dierence of pressure. i A The accompanying drawingsillustratean 2o vembodiment of this idea, '.Fg. 1 being a planl of an aeroplane, with parts broken away or omitted, constructed according to the invention. v Fig. 2 is a detail in section As shown in the drawings, the fuselage 25 consists of an outer skin or wall 5 and an y inner wall 6, these being spaced apart. These walls will be made air tight with re- .spectto the space between them, and by any suitable means the air Awill be exhausted `30 to form the'desired va'ccum. For supporting the walls. against pressure,"and maintaining the same 1n spacedv relation, I provide, ribs or beams 7, conveniently of I secl tions the anges ofl which are bolted to the S5 walls as indicated at 8 or are fastened in Vor the space between 'the walls otherwise di? vwith'respect tol lightnessandcheapness of 192e." ysmal No. 124,951.v

any other suitable way, kand a packing 10 of asbestos or other suitable material is clamped -.between the walls'and the beams to make an air tight jointat the bolts, and prevent conduction of heat thru the ribs between the walls; the beams maybe perforated at 7 for communication between the sections, or the beams may be made solid,

vided intocompartments from which the air may b e exhausted by any suitable means. As many beams will be used as may be de# sired or necessary, according to the strength desired or the resistance'to be supported.

This .construction has the advantage of '5D i lightnessso desirable-in aerial structures. The walls arepreferably made of aluminum or other metal or alloys thereof and when so constructed will be light and strong and Ahave the, high insulating qualities referred '55 to, being' thereby superior to the insulating packing or fillings of any kind, with respect both to heat insulating qualities and also construction.

I claim: An 'aeroplane fuselage' having double-air tight walls with a vacuum space therebeltween-and ribs at intervals between the walls in'said space, said lribs being fixed to the respective walls, and heat insulating packing between the 'ribs and the 'walls In testimony whereof, l do affix my signature.
